@szymon_dybczak did you see this post yesterday about Choropleth maps not working?: https://community.databricks.com/t5/warehousing-analytics/choropleth-maps-stopped-working/td-p/13199... 

I wonder if a similar fix can happen for this situation, as it could be browser-related

Could you also try opening Databricks in a different browser? Not that this is a proper solution 😊.

All the best,
